Tanah berlendut merupakan suatu jenis tanah yang bersifat sangat lunak, karakteristik struktur penyusun tanah tersebut adalah berbutir halus (Lempung).Stabilisasi tanah adalah carayang digunakan untuk menangani perbaikan lapisan struktur tanah yang masih kurang baik dalam spesifikasi penggunaanya.Pada penelitian berikut ini penulis mempergunakan Bahan tambahan labu kayu bakar dan semen portland tipe 1.Pada hasil penelitian menunjukkan Tanah dari Kecamatan Mojoroto Kota Kediri Jawa Timur berjenis lanau. Pada metode USCS tanah tersebut masuk dalam jenis lempung CH, dan kategori tanah A-7 pada AASHTO yang disimpulkan bahwa tanah tersebut adalah berlempung sedang hinggatinggi.Dari hasil pengujian pemadatan tanah asli Unsoaked didapatkan nilai PROCTOR sebesar 8,72%, sedangkan pada tanah Asli Soaked sebesar 1,23%.Pada penambahan abu kayu bakar sebesar 3% beserta Semen Portland sejumlah 4% memberikan kenaikan Nilai uji PROCTOR hingga menjadi 29,72% pada tanah asl i.Ketika Benda uji dilakukanpemeraman terbukti memberikan peningkatan nilai kepadatan dan ketika dilakukan pemeraman selama 7 hari nilai PROCTOR relatif konstan. Pada Swelling test menunjukkan hasil yang semakin bagus ketika persentase bahan campur abu kayu bakar semakin banyak. Dari pengembangan tanah asli sebesar 4,9% menjadi 0,038% pada pengembahan tanah asli, abu kayu bakar 7% dan semen portland 4%.

Beton merupakan salah satu unsur penyusun bangunan paling vital mulai dari kolom,bata, paving hingga jalan terbuat dari beton sehingga penggunaan beton cenderung tinggi. Beton sering digunakan sebagai bahan penyangga utama pada suatu bangunan maka diperlukan kualitas yang baik, namun hal tersebut tidak di sertai dengan kualitas bahan yang kian menurun,makadiperlukan inovasi penambahan bahan baru yang setidaknya dapat mengurangi kebutuhan bahan utama pembuat beton, salah satunya pemanfaatan limbah genteng dan limbah batu silika Hasil dari pengetesan uji kuat tekan beton dengan penambahan serbuk genteng terhadap semen dan penambahan pasir silika terhadap pasir sungaimendapatkanKuat tekan paling tinggi di hasilkan oleh beton dengan penambahan masing masing 10% pada sampel 2 yang mencapai K-258Dari hasil rata-rata kuat tekan beton dengan campuran masing masing 10% mencapai nilai K-251 yang berarti cukup mencapai target yaitu K-250 Hasil dari pengetesan daya serap beton terhadap air dengan campuran beton dengan bubuk limbah genteng dan pasir silika adalah, daya serap tertinggi di hasilkan oleh beton sampel 3 dengan campuran masing masing sebanyak 20% dengan nilai 0,187 liter setelah perendaman selama 24 jam Dari rata-rata keduanya memiliki nilai yang berbeda yaitu 0,113 liter untuk beton dengan campuran 10% dan 0,133 liter untuk beton dengan campuran 20% Kata kunci : Serbuk Limbah Silika, Serbuk Limbah genteng, Beton.

Foundation is a structure that functions to withstand loads above it and the load itself. These loads are transferred to the ground directly. The case study in this plan is the construction of the Dwi Indah Building in Selodono Village, Kediri Regency. The building has a building area of 308 m2 and a height of 16 m, with the function of the building as an inn. In this planning, the type of pile foundation is used. A Pile foundation is a type of deep foundation that divides the gravity load evenly on the ground and makes the structure of the building strong and strong. The purpose of this planning is to plan a strong pile foundation that is able to withstand the load of the Dwi Indah Building. The method used in this planning is the Meyerhoff method, with a pile diameter of 30 cm and a foundation depth of 800 cm. From the calculation results obtained (single pile bearing capacity) Pall= 42.62 tonnes greater than (maximum pile load) Pmax= 26.00 tonnes (SAFE). For the control of the yield of the buckling factor, the result is (buckling) ω= 178.61 kg/cm2 <(base stress) σ = 2400 kg/cm2 (SAFE).

Milkfish with high protein content has potential as the raw material of HPI and HPI review of the fish has not been implemented. This study aims to determine the effect of the concentration of the enzyme papain to the quality of the protein hydrolyzate of fresh milkfish (Chanos Chanos Forsskal). This study was conducted laboratory experimentally. The trial design used in this study was complete random design to analyze the effect of papain enzyme concentrations (4%, 5%, and 6%) toward the quality of protein hydrolyzate of milkfish. Protein hydrolyzate of milkfish could be produced by enzymatic hydrolysis using papain enzyme. The observed parameters were the yield and the proximate level (level of protein, fat, water, and ash). Type of enzyme and concentration had significant effect toward the proximate level of protein, fat, water, and yield, but not significant toward the level of ash. The optimal condition to hydrolyze milkfish flesh into protein hydrolyzate was by using papain enzyme with concentration of 5% (b/v). Keyword: Milkfish, hydrolyzate of protein, enzyme papain

Quality education requires a quality learning process. Quality learning is certainly designed in learning activities that use learning methods that are in accordance with the eyes taught by the teacher so as to assist the teacher in giving directions so that students can understand the content delivered by the teacher. In reality, education in Indonesia has decreased the quality of learning in the context of an independent curriculum. There are research findings called learning loss and learning gap devices in this problem. So it is expected that subject teachers must be able to restore the declining level of learning quality. So researchers use a problem-based learning model. Where this problem-based learning model can solve problems and increase students' knowledge. The purpose of the study was to analyze the implementation of problem-based learning in improving the quality of PPKn learning at SMP Negeri 19 Malang. The method used in this research is qualitative case study method. Data collection techniques based on observation, interviews and document research. The result of this study is the application of the ICT-assisted problem-based learning model showing that a significant change because students are directed to examine problems in learning activities using problem-based teaching methods that have a positive impact on student achievement outcomes. Based on the results of the research, researchers can conclude that the application of ICT-assisted problem-based learning models in class VIII PPKn subjects of SMP Negeri 19 Malang students can solve problems in groups given by teachers.
